How to Fix a Sticking Door
Before you attempt to fix a sticky door, identify why the door is sticking in the first place. Here are three common reasons doors stick:
- Excess humidity

You may also be able to feel dents in the door where it rubs against the frame. These clues will help you determine where your door is rubbing.

How Can I Prevent My Door From Sticking?
Look for an indoor thermometer that includes a hygrometer to measure humidity. If the hygrometer shows more than 70% humidity, you may want to invest in a dehumidifier.
